SUPPORT FOR SKATE Application filed January 24, 1928,

My. invention relates to ice skates, and" more particularly to an ice skate having an improved for the runneror blade of the skate.

One of the objects of my present invention.

an improved blade or runner is light in weight yet provides a mounting in which the runner or blade of 'tlieskate is secured of pronounced rugge'dnessand.strength, and which holds the runner in true position with out danger of warping or bending.

Another object of sides in the provision for the blade or runner al, preferably sheet steel, and bent or folded so as to provide a reentrant seat or pocket having reinforced side walls and which pocket is adapted to snugly receive the runner or blade of the skate.

is to provide of a tubular support Yetanother obiectoi my invention 're sides in the process by which'iny improved tubular support may be formed from a strip of sheet metal'by means ofa bending or folding operation and wherein the metal 1s provided with a reentrant pocket for the re ception of the skate runner and wherein the free edges of the metal blank are interlocked to provide a substantial 0118-131608 construction of great strength and compact arrangement. This and other objects ofrny invention will be apparent from a perusal of the following specification, and. taken in connection with the accompanying Figure 1 is skate.

relates to the, construction of the tubular support and the mannerof holding the runher mountedtherein'and also to the process by which the support is tormedandthe runner assembled in position.

In order clearly to explain the construction of my improved support I will describe it by reference to the process in which it is made. I prefer to start-with a sheet'metal blank 12, preferablyor sheet steel and preferabiy otrectan a strip of pronounced length may be used and the separate blanks c'uttrom this strip.- However, in the present instance Isha'll refer to a strip of the proper length for forming one tubular support. A

of the drawings. In the first step in the formation of this blankI bend one of the marginal edges thereof downwardly to provide a flange 14 and ginal edge, which is considerably wider,

downwardly also to provide another flange 16 which has a right angle extension/18 projecting horizontally'as shown in Figure 4 and this flange in turn is extended again upwardly to provide a portion of flange 2O lying parallel and spaced apart from the flange 16, as clearly shown in Figure i. These flanges extend the length of the blank. Either simultaneously with the bending of these flanges, or before or after, I also provide the blank 12 longitudinally thereof with a substantially centrally located upstanding hollow ridge 22 which in cross section is ofU respect to its width. This hollowfridge is provided with two parallel upstanding walls 24 and 26 joined by a top flange 28 which in fact is a' continuation of the walls 24: and 26 only extending at right angles thereto. also, simultan eously with the formation of the flanges 14,16, 18 and 20 and,' or, with the formation of the ridge 22 or before or thereafter, I also cut from'the' end of the blank Theinaterial of the blank is cut away where the ridgeis located to provide the slot 34.

next step to fold the blankinto the form shown in Figure 5'. In this operation I prefer to' s'wing or curl the longitudinal edges of the blank on" each. side of the ridge ular shape and relatively fragment of this blank is shown in Figure I bend the opposite marshape, being relatively deep with r 12 the two spaced aparttongues some 32. I

upwardly so as toforrn'curyed side walls 36' and 38' and the freeflanged ends of these walls are carried upwardiy to a point above the top portion '28 oftheridgeand so that the flanges 16, 18 and 20 overlap the flange 14 and interlock therewith, with the lower portion of the flange 14 lying on the top 28 of the ridge and the lower portion 42 of the flange 16 lying also on the top 28 of the ridge. Thus I provide twotubular portions 44 and 46, one lying on each side of the walls 24 and 26 of the ridge with the flanges 14, 16, 18 and 20 interlocking and overlying and upon the fiange28 of the ridge all serving to form a very compact and strong tubular construction with the recess or pocket formed by the walls 24 and 26 of the ridge and which pocket lies between the tubular portions 44 and 46. Preferably after a tube is bent into form, as shown in Figure 2, I also die-press or pinch the tongues 30 and 32 together in the manner illustrated in Fig ure 5 to provide a relatively blunt or rounded nose both at front and back of blank and with an intervening slot 34 lying in the plane of the pocket formed by the walls 24 and 26. Each end of the blank is formed similarly except that the front is given a slight upward turn to correspond with the 'upturn of the runner.

The skate runner or blade is inserted in this pocket and between the walls 24 and 26 and snugly in contact therewith. The upper edge 48 of the runner formedabuts the end face of the wall 28 of the ridge and by reason. of the depth of this pocket the skate blade is firmly held between the two side walls 24 and 26 and the spaced apart tubes 44 and 46 in rigid relation throughout its length. I prefer to solder the runner 50 in position as shown by means of the solder 52. Nhen the runner is seated in the pocket. the front portion of the runner 54 will seat in the front slot 34, while the rear portion of the runner will seat in the rear slot. One of the final finishing steps consists in removing the metal of the ridge from a point removed from the front and rear inwardly as indicated at 52 and 54 in the drawings.

By reference to seen that I have provided a very strong and compact arrangement for supporting the skate runner throughout its length in a very firm manner so as to preclude any warping or twisting of the blade out support is formed of a single blank of sheet metal by simple folding and bending operations and wherein the walls of the blank are provided with a very rigid pocket or recess and formed on each side thereof with tubular supports merely by appropriately bending the sheet of metal, preferably upwardly and upon itself to form the spaced apart tubes and the intermediate pocket. It will be seen that the pocket is-originally formed by the upstanding ridge and that the tubes are formed by curling the free edges of the longitudinally extending the foregoing it will beof its socket. I also provide a very convenient and economical construction whereby the ed in said seat, said blank upwardly and above the ridge so as to rest on the top ofthe same. In this construction it will be seen that the folded portions lying longitudinally of thefree edges of the blank, by reason of their interlocking engagement with each other and upon top of theridge, provide a most compact and rugged construction for the purposes de- "and curved upwardly to a point above the bottom wall of said pocket to overlie the same in interlocking runner seated in said pocket.

A skate having a longitudinally extend ing support consisting of a blank of sheet metal having a substantially oval shape with the top and bottom thereof substantially flat, the bottom wall being formed of a re-entrant fold having parallel spaced apart sides and a bottom wall extending parallel toand in contact with the top wall to provide a pocket, the upper wall of said support including interlocking portions of the free longitudinal edges of the original blank and a skate runner mounted in said pocket.

3. A skate having a tubular support formed of a sheet metal blank, said blank being tubular in shape with one wall of the tube extending inwardly to provide a re entrantly disposed pocket, the'free edges of the blank being interlocked and forming a part of the opposite wall and a skate runner mounted in said pocket.

4. In an ice skate the combination of a runner support of tubular cross section having its upper wall provided with upstanding interlocking flanges and with its lower wall provided with an inward fold having spaced apart walls and the intercommunicating facial wall contacting with the inner surfaces of the interlocked flanges of the upper wall and a runner mounted in said re-entrant fold. v
